how do i fix animation hitches

To fix animation hitches, you can follow several strategies discussed in various WWDC sessions:

1. Smoothly Animate Constraints:

   • In the session Compose interactive 3D content in Reality Composer Pro, it is suggested to increment and decrement the weight of how much the position is driven by inverse kinematics (IK) and how much it is driven by the base pose over time. This smooth transition can help avoid hitches when starting or ending animations.

2. Use Animation Actions:

   • The same session also discusses using animation actions to sequence actions together over a duration of time, similar to cutscene animations in games. This can help in managing complex animations smoothly (Compose interactive 3D content in Reality Composer Pro).

3. Blend Shape Weights:

   • Gradually increment or decrement blend shape weights with an easing function to ensure smooth transitions between states (Compose interactive 3D content in Reality Composer Pro).

4. Continuous Velocity in UI Animations:

   • For UI animations, using continuous velocity can help maintain smooth transitions. SwiftUI animations can preserve velocity at the end of a gesture, which can be applied to UIView animations as well (Enhance your UI animations and transitions).

5. Debugging Tools:

   • Utilize tools like the RealityKit debugger to track down and fix issues in your entity hierarchies and components. This can help identify and resolve the root causes of animation hitches (Break into the RealityKit debugger).
